Procedure

The title compound was prepared using General Experimental Procedure A (Suzuki coupling reaction) from 2-bromobenzo[4,5]imidazo[1,2-a]pyrimidine and (4-cyano-3-fluorophenyl)boronic acid on a 0.1 mmol scale. The residue was washed with water (3×5 mL), EtOAc (3×2 mL), and DCM (3×2 mL) and dried under high vacuum to afford 4-(Benzo[4,5]imidazo[1,2-a]pyrimidin-2-yl)-2-fluorobenzonitrile (T747) as a orange solid (10 mg, 35%). 1H NMR (400 MHz, DMSO-d6): δ 9.74 (d, J=6.8 Hz, 1H), 8.46 (d, J=10.8 Hz, 1H), 8.41-8.38 (m, 2H), 8.19 (t, J=7.6 Hz, 1H), 7.98 (d, J=6.8 Hz, 1H), 7.90 (d, J=8.4 Hz, 1H), 7.60 (t, J=7.2 Hz, 1H), 7.45 (t, J=7.2 Hz, 1H); MS (ESI) m/z [M+H]+289.
